Funda demasiado pequeña

El saco es un buen producto pero es casi imposible meterlo en su funda original, esta bien llevar todo lo mas compactado posible pero creo que en este caso es muy difícil; hemos tenido que utilizar otra funda .

User temperature

On all of our sleeping bags, we display the comfort temperatures tested by an independent laboratory (AITEX) according to European standard NF ISO 23537 - 2017. The temperature rating is the lower limit at which the user is generally in thermal equilibrium and feels neither too cold nor too hot in a relaxed pose (for a standard woman and in normal conditions of use). Choose your sleeping bag according to the latter.

What are the "limit" temperatures of use?

Limit temperature: temperature at which the user huddled up in the sleeping bag is generally in thermal equilibrium and feels neither too cold nor too hot (defined for a standard man under normal conditions of use).

However, what you need to know about temperatures

A sleeping bag does not generate warmth but retains the warmth produced by the body. If you feel tired and cold and slip into a cold and damp sleeping bag, you are likely to feel cold, however good it is! These temperatures therefore depend on the person's resistance to the cold (bulk, fatigue, etc.), their equipment (mattress that insulates from the cold, etc.), their clothing (naked, underwear, etc.) and the weather conditions (humidity, wind, etc.).

For greater comfort before sliding into your sleeping bag

Dress simply (just 1 layer of clothing is enough). Keep your head, hands and feet warm: hats, gloves, socks, hand or feet warmers, rubdown, etc. A bottle full of hot water can be used as a hot water bottle (as long as it will not open accidentally!) Contract your muscles (70% of the energy consumed is transformed into heat). However you should do this without moving as this can cause drafts of cold air. Use a liner sheet, ideally made of silk, to optimize the warmth inside your sleeping bag.


"Generous" mummy shape: wide at the shoulders and more narrow at the feet to optimize thermal insulation (no heat loss) and compact size, while retaining some freedom of movement. Width at shoulder height 30.1" and at feet height 12.6" in size L. Ergonomic hood with drawstring. 2 side zippers with double sliders, lined with a flap (sausage-shaped) made of insulating padding (thermal bridges) and side openings.

Size XL 2.3 lbs, user between 6'1" and 6'7". Dimensions folded: H 13" Ø 7.1". Volume 8 liters. Try your sleeping bag before buying it to choose the right size to ensure your comfort.


This sleeping bag is guaranteed for a period of 5 years from the date of sale indicated on the receipt. The product covered by the warranty will be repaired or exchanged free of charge. The warranty covers the defects of your sleeping bag apart from those resulting from normal wear and tear and improper use. This special 5-year warranty will only be granted upon presentation of the product and sales receipt.



Storage instructions

Easily store your bag by stuffing it in its bag, feet end first. To maintain its fill power, which is what provides the thermal insulation, remove the bag and store it flat in a dry place.
